Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a stirring blade and a snow melting machine having the same. Background Technology

[0002] Snow melting machines are a new type of commercial cold drink machinery developed in recent years. They are classified into single-cylinder, double-cylinder, and triple-cylinder types according to the number of cylinders, and are mainly used in catering scenarios such as cold drink shops, cafes, and hotels.

[0003] Chinese Patent CN223221307U discloses a novel stirring blade belonging to the field of cold product stirring technology. It includes an assembly ring with at least two spiral blades spirally arranged on it. The at least two spiral blades are spaced apart, and each has a pusher plate at its end. The pusher plates are inclined along the spiral direction of the spiral blades and connected to each other by connecting sleeves. The connecting sleeves are coaxial with the assembly ring and have connecting holes. The spaced-apart spiral blades create ample space, and pusher plates are only provided on at least two of the spiral blades.

[0004] However, the above-mentioned stirring blades have the following disadvantages: the middle section of the two spiral blades lacks connection, and the spiral blades are prone to deformation during the stirring and pushing process, which affects the normal operation of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a stirring blade and a snow melting machine having the same, which has the advantages of stable stirring blade connection, high strength, large pushing area, and high discharge efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stirring blade, comprising a blade body, the blade body comprising a positioning ring and a spiral blade, the spiral blade being fixed on the positioning ring, the blade body comprising at least two spiral blades, the spiral blade comprising a bottom near the positioning ring and a middle portion located in the middle of the spiral blade, a first connecting piece being provided between the two spiral blades, the first connecting piece being arc-shaped, and one end of the first connecting piece being connected to the bottom of the spiral blade, the other end of the first connecting piece being located in the middle portion of the other spiral blade.

[0007] By adopting the above technical solution, during the operation of the blade body, the external driving force drives the blade body to rotate. The blade body is assembled in the refrigeration equipment through the positioning ring. When the blade body rotates, the cold product is scraped off by the spiral blade. The cold product moves towards the front end under the pushing action of the spiral blade, which facilitates feeding. The blade body is connected by the first connecting piece, which improves the overall strength of the stirring blade and prevents deformation and damage during the rotation of the spiral blade. At the same time, the first connecting piece can push the material after the blade body scrapes the material, which increases the pushing area and pushing efficiency during use. In addition, the first connecting piece is designed to be arc-shaped, which improves the toughness of the first connecting piece and prevents damage and breakage caused by excessive resistance when the first connecting piece rotates.

[0008] A further feature of this invention is that the positioning ring is provided with a first connection point and a second connection point, one end of the spiral blade is connected to the first connection point, and the other end of the spiral blade is connected to the second connection point, with the first connection point and the second connection point being arranged opposite to each other.

[0009] By adopting the above technical solution, the helical blade is fixed to the positioning ring through the first connection point and the second connection point, which facilitates the positioning of the helical blade. At the same time, the two helical blades are arranged opposite each other, so that the center of gravity of the blade body is located at the center, preventing damage caused by the eccentric rotation of the blade body during equipment use.

[0010] A further feature of this invention is that the blade body further includes a second connecting piece, the second connecting piece being arc-shaped, one end of the second connecting piece being fixed to the positioning ring, the other end of the second connecting piece being fixed to the end of the spiral blade away from the positioning ring, and the middle section of the second connecting piece being fixedly connected to the spiral blade.

[0011] By adopting the above technical solution, the second connecting piece connects the two spiral blades and is fixed on the positioning ring at the same time, which further improves the overall strength and deformation resistance of the blade body. The second connecting piece is arc-shaped, which improves the toughness of the second connecting piece. At the same time, it increases the contact area between the blade body and the cold product, thereby improving the scraping and pushing efficiency of the equipment.

[0012] A further feature of this invention is that the side wall of the second connecting piece is provided with a scraping slope.

[0013] By adopting the above technical solution, when the blade body rotates, it drives the second connecting plate to rotate, so that the scraping inclined surface contacts the cold product and scrapes off the cold product under the action of rotation. The scraping inclined surface is inclined, which reduces the resistance in the scraping process and facilitates scraping.

[0014] A further feature of this invention is that the area of ​​the blade at the end of the spiral blade furthest from the positioning ring is increased to form a pushing section.

[0015] By adopting the above technical solution, when the cold product is pushed to the pusher section along the spiral blades, the pusher section rotates and pushes the cold product to the outlet. The blade area of ​​the pusher section is increased, which improves the pushing efficiency of the front end of the spiral blades.

[0016] A further feature of this invention is that the front end of the pusher is provided with a front end plane, the front end plane is parallel to the plane where the positioning ring is located, and the front end plane is perpendicular to the discharge direction.

[0017] By adopting the above technical solution, when the stirring blade is working, the cold product is pushed towards the discharge port by the pushing part. The direction of the pushing force is changed by the front plane, so that when the cold product is pushed to the vicinity of the discharge port, the cold product is subjected to the pushing force in the same direction as the discharge direction, which facilitates the discharge.

[0018] A further feature of this invention is that the blade body further includes a rotating shaft, and a positioning structure is provided between the rotating shaft and the blade body, wherein the rotating shaft is inserted into and positioned with the blade body through the positioning structure.

[0019] By adopting the above technical solution, it is easier to position the mixing blades during installation, thus improving the ease of installation for users.

[0020] A further feature of this invention is that the positioning structure includes an insertion plane and a positioning groove. The insertion plane is located on the front side wall of the rotating shaft, and the positioning groove is formed on the blade body corresponding to the insertion plane. The insertion plane and the positioning groove are inserted and positioned together.

[0021] By adopting the above technical solution, when installing the stirring blade, the insertion plane of the rotating shaft is inserted along the positioning groove guide, which avoids the rotating shaft from rotating relative to the positioning groove. This facilitates the positioning of the stirring blade and improves the installation stability between the stirring blade and the rotating shaft. At the same time, it ensures the concentricity of the stirring blade, improves the installation accuracy, avoids eccentric loads that increase the motor load, and increases the service life of the equipment.

[0022] Another technical objective of this utility model is achieved through the following technical solution: a snow melting machine, including a material barrel, a stirring blade installed inside the material barrel, an evaporator installed inside the material barrel, the evaporator being located outside the rotating shaft, and the stirring blade being rotatably mounted on the outer periphery of the evaporator via the rotating shaft.

[0023] By adopting the above technical solution, the equipment is cooled by the evaporator during operation, and the cold products on the outer wall of the evaporator are scraped off by the stirring blades. At the same time, the cold products are pushed in the discharge direction by the rotation.

[0024] A further feature of this invention is that the evaporator includes an inner liner and an outer shell, with an evaporation chamber formed between the inner liner and the outer shell. The evaporation chamber is provided with a plurality of parallel annular ribs, each annular rib having a notch. The notches of adjacent annular ribs are staggered, forming a labyrinthine flow channel within the evaporation chamber. The evaporator is provided with a liquid inlet pipe and a gas outlet pipe. The liquid inlet pipe is connected to the inlet end of the labyrinthine flow channel, and the gas outlet pipe is connected to the outlet end of the labyrinthine flow channel.

[0025] By adopting the above technical solution, the refrigerant enters the labyrinth flow channel along the liquid inlet pipe and flows from the gap of the annular rib to the gap of the next annular rib. This facilitates the uniform filling of the refrigerant into the evaporation chamber, allowing the refrigerant to uniformly evaporate and absorb heat in the evaporation chamber and be discharged along the gas outlet pipe. The labyrinth flow channel allows the refrigerated product to fully absorb heat, facilitating product formation in the material tank and thus improving the refrigeration effect and discharge efficiency.

[0026] In summary, this utility model has the following beneficial effects: 1. By using a first connecting piece and a second connecting piece between the spiral blades, the overall strength of the mixing blades can be improved, and the efficiency of scraping and pushing materials can be increased.

[0027] 2. By using a scraping slope on the side wall of the second connecting plate, the scraping resistance is reduced and the scraping of material by the mixing blade is facilitated.

[0028] 3. By setting a front plane at the front end of the push section, the direction of the fan blade thrust can be adjusted, which facilitates material discharge. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] A stirring blade, such as Figure 1-4 As shown, the device includes a blade body 1, which includes a positioning ring 11 and helical blades 12. During operation, an external driving force drives the blade body 1 to rotate. The blade body 1 is assembled inside the refrigeration equipment via the positioning ring 11. The helical blades 12 are fixed on the positioning ring 11, and the blade body 1 includes at least two helical blades 12. When the blade body 1 rotates, the helical blades 12 scrape off the refrigerated product. The refrigerated product moves towards the front end under the pushing action of the helical blades 12, facilitating feeding. The helical blades 12 include a bottom near the positioning ring 11 and a middle part located in the middle of the helical blades 12. A first connecting piece 1 is provided between the two helical blades 12. 3. One end of the first connecting piece 13 is connected to the bottom of the spiral blade 12, and the other end of the first connecting piece 13 is located in the middle of another spiral blade 12. The blade body 1 is connected by the first connecting piece 13, which improves the overall strength of the stirring blade and prevents the spiral blade 12 from deforming and being damaged during rotation. At the same time, the first connecting piece 13 can push the material after scraping the material from the blade body 1, which increases the pushing area and pushing efficiency during use. In addition, the first connecting piece 13 is designed to be arc-shaped, which improves the toughness of the first connecting piece 13 and changes the direction of the force on the cold product when scraping the material, preventing damage and breakage caused by excessive resistance when the first connecting piece 13 rotates, and reducing the rotation torque of the motor.

[0040] like Figure 1 , 4As shown, in this embodiment, the positioning ring 11 is provided with a first connection point 111 and a second connection point 112. The end of one helical blade 12 is connected to the first connection point 111, and the end of the other helical blade 12 is connected to the second connection point 112, which facilitates the positioning of the helical blades 12. The first connection point 111 and the second connection point 112 are arranged opposite to each other, so that the two helical blades 12 are arranged facing each other, and the center of gravity of the blade body 1 is located at the center, preventing damage caused by the eccentric rotation of the blade body 1 during equipment use. In other embodiments, more helical blades 12 can be added. The number of blades is increased to enhance the blade area and improve mixing and scraping efficiency. Furthermore, the blade body 1 includes a second connecting piece 14. One end of the second connecting piece 14 is fixed to the positioning ring 11, and the other end is fixed to the end of the spiral blade 12 away from the positioning ring 11. Simultaneously, the middle section of the second connecting piece 14 is fixedly connected to the spiral blade 12. The second connecting piece 14 connects the two spiral blades 12 while being fixed to the positioning ring 11, further improving the overall strength and deformation resistance of the blade body 1. Additionally, the second connecting piece 14 is arc-shaped, enhancing its toughness. Simultaneously, the contact area between the blade body 1 and the cold product is increased, thereby improving the scraping and pushing efficiency of the equipment. A scraping slope 141 is provided on one side of the second connecting piece 14 to reduce the resistance during the scraping process, prevent excessive resistance from affecting the operation of the equipment, facilitate scraping, and improve the durability of the equipment. In addition, the blade area of ​​the end of the spiral blade 12 away from the positioning ring 11 is increased to form a pushing part 15. In this embodiment, the discharge direction is parallel to the axis of the blade body 1, and the material is discharged from the positioning ring 11 to the pushing part 15. When the discharge stops, the blade body 1 rotates, and the pushing part 15 reverses. The cold products are pressed backward by force to facilitate mixing. The front end of the pusher 15 is provided with a front end plane 151, which is perpendicular to the discharge direction. When the cold products are pushed to the pusher 15 along the spiral blades 12, the pusher 15 rotates to push the cold products out of the discharge port. The blade area of ​​the pusher 15 is increased to improve the contact area of ​​the spiral blades 12 pushing the products to the front end, thereby improving the pushing efficiency. At the same time, the front end plane 151 changes the direction of the pushing force so that when the cold products are pushed to the vicinity of the discharge port, the cold products are pushed in the same direction as the discharge direction, which facilitates discharge.

[0041] like Figure 3 , 5As shown in Figure 6, in this embodiment, the blade body 1 also includes a rotating shaft 2. A positioning structure 3 is provided between the rotating shaft 2 and the blade body 1. The positioning structure 3 includes an insertion plane 31 and a positioning groove 32. The insertion plane 31 is located on the front side wall of the rotating shaft 2. The insertion groove is provided with a positioning groove 32 into which the rotating shaft 2 can be inserted. The insertion plane 31 and the positioning groove 32 are inserted and positioned. When the stirring blade is installed, the insertion plane 31 of the rotating shaft 2 is guided and inserted along the positioning groove 32 to prevent the rotating shaft 2 from rotating relative to the positioning groove 32. This facilitates the positioning of the stirring blade and improves the installation stability between the stirring blade and the rotating shaft 2. At the same time, it ensures the concentricity of the stirring blade, improves the installation accuracy, avoids eccentric loads that increase the motor load, and increases the service life of the equipment.

[0042] like Figure 2 , 7 As shown in Figure 8, in this embodiment, the stirring blade is used for stirring cold products inside the snow melting machine. The snow melting machine is equipped with a material tank 4, and an evaporator 5 for cooling is installed inside the material tank 4. The evaporator 5 is located outside the rotating shaft 2, and the stirring blade is rotatably mounted on the outer periphery of the evaporator 5 via the rotating shaft 2. The evaporator 5 includes an inner liner 51 and an outer shell 52, forming an evaporation chamber 53 between the inner liner and the outer shell 52. Multiple parallel annular ribs 54 are provided inside the evaporation chamber 53. Each annular rib 54 has a notch 541, and adjacent notches 541 are staggered, so that the evaporation chamber 53... A labyrinth-type flow channel 55 is formed. The inner liner 51 has a liquid inlet and an air outlet. The refrigerant flows in from the liquid inlet pipe 56 and enters the labyrinth-type flow channel 55 through the liquid inlet. It evaporates and cools in the labyrinth-type flow channel 55 and is discharged from the air outlet along the air outlet pipe 57. This facilitates the uniform filling of the refrigerant in the evaporation chamber 53, allowing the refrigerant to evenly evaporate and absorb heat in the evaporation chamber 53 and be discharged along the air outlet pipe 57. The labyrinth-type flow channel 55 allows the cold product to fully absorb heat, which facilitates the formation of the product in the material tank 4, improves the efficiency of cold product production, and thus increases the output and improves the equipment's output efficiency.

[0043] The basic working principle of this utility model is as follows: The blade body 1 is provided with at least two spiral blades 12. The spiral blades 12 rotate and stir under the action of external force. The beverage added is cooled by the evaporator 5 to form a cold product. The cold product is attached to the outer wall of the evaporator 5. The spiral blades 12 scrape the material and push the cold product out. A first connecting piece 13 is provided between the two spiral blades 12, which improves the overall strength of the stirring blade, makes the stirring blade connection stable, prevents the spiral blades 12 from deforming and being damaged during rotation, and increases the pushing area and pushing efficiency during use. The first connecting piece 13 is arc-shaped to improve the toughness of the first connecting piece 13, prevent the first connecting piece 13 from being damaged and broken due to excessive resistance during stirring and scraping, and improve the durability of the equipment.
